THOMAS L. MOORE, OF NEW YORK, N. Y.

PAVING-JOINT.

Specification of Letters Patent.

Application filed January 23, 1912. Serial No. 672,871.

ures of reference marked thereon, which form a part of this specification.

Figure 1 is a plan view of the invention, as applied, with parts broken away. Fig. 2 is a perspective view of the invention, as

applied, with parts in section. Fig. 3 is a perspective view of the invention, partly broken away.

The invention relates to joints for paving, primarily designed for use with wooden block pavements to automatically take up the expansion and contraction of the paving ,caused by the heat and cold of different seasons of the year.

The invention consists in the novel con struction and combinations of parts, as hereinafter set forth.

In the accompanying drawings illustrating the invention, the numeral 1, designates a portion of a wooden block pavement; 2, a concrete foundation therefor, and 3, a mortar'bed between the wooden blocks and said foundation.

4, is my joint, which is preferably placed in position longitudinally of the paving along the center line of the roadway. This joint is provided with opposite lateral flanges 5, and 6, having preferably an angular relation to efih other and converging toward their lower ends to leave a V-form interval between the flanges, said interval being covered over at the top by an extension or extensions of the flanges, preferably a substantially horizontal extension 8 of the flanges, said extension projecting toward and lapping over the top edge of the other flange. The opposite flanges of the joint have outward extensions or shoulders 9, 9, extending over the wooden blocks or the paving at the two sides, said. shoulders serving to transmit the strain of the load of passing vehicles through the blocks or paving directly to the foundation, and relieving the joint of this strain.

Suitable means areprovided to lock the joint in place, said means consisting preferablyof lower lateral extensions 10, 10, located in the mortar bed and extending beneath the paving or blocks at the two sides of the interval wherein the joint is located.

The entire joint, consisting of the opposite flanges the cover extension, the upper shoulders, and the base locking extensions is adapted to be formed in one piece, with the cover extension welded upon one of the opposite flanges, although this is not necessarily the case, and both flanges are adapted to be moved toward each other from their lower ends as centers under the influence of the expansion of the paving; and to auto- Patented Oct. 8, 1912.

matically move away from each other owing to their spring character when the weather becomes colder, the cover extension having sliding lapping engagement with the top of the opposite flange to keep the interval between the flanges always covered.

The sides of the paving or of the wooden blocks covering the roadway are held in position by the curbing 11, in the usual manner, so that the expansion and contraction of the paving takes effect at the center line of the roadway. The oint may however be placed in position transversely of the road way, or in other suitable relation thereto, according to the requirements in different cases.

Various changes in the form, proportion and minor details of construction of my joint may be made without departing from the principle or spirit of the invention.

Having thus described my invention,what I claim as new and desire to obtain by Letters Patent is l. A spring metal paving joint consisting of opposite movable angularly related flanges, separated from each other by a V- form interval, upper outward extending shoulders, and a cover for said interval, having connect-ion with one of said flanges to move therewith.

2. A spring metal paving joint, consisting of opposite movable angularly related flanges separated from each other by a V- form interval, a cover extension of one of said flanges for said interval, upper outward extending shoulders, and a lateral base flange-extension.

3. In a paving joint, a horizontally extending anchor member under thepaving, a movable supporting member extendingupward from the anchor member, and bearing laterally against the paving, and a horizontally-movable bridge member carried by the supporting member, movable therewith to keep the joint closed and having means bearing against the top of the paving to take the strain of a load from the supporting member.

4. In a paving oint, a laterally extending anchor member for location beneath the paving, movable supporting members extending upward from the anchor member and separated from each other by an interval, said supporting members being designed to bear-laterally against the paving and having upper lateral extensions designed to bear upon .the top of the Paving, and a horizontally movable bridge member carried by one of the supporting members, having extension across said interval, and a sliding bearing upon the upper lateral extension of the supporting member at this side.

5. In a paving joint, a. laterally extending anchor member for location beneath the paving, a movable supporting member ex tending upward from and having ,aspring connect-ion with the anchor member and being designed to bear laterally against the paving and a horizontally movable bridge member carried by said supporting member and being movable therewith to keep the joint closed.

6. In a paving joint, a laterally extending anchor member for location beneath the paving, a movable supporting member extending upward from and having a spring connection with the anchor member and being designed to bear laterally against the paving, a horizontally movable bridge member carried by said supporting member, movable therewith to keep the joint closed and having a lateral extension designed to bear upon the top of the paving to take the strain of a load from the supporting member.

7. In a paving joint, a laterally extending anchor member designed for location beneath the paving, movable supporting members extending upward from said anchor member, separated from each other by an interval, and having a spring connection with the anchor member, said supporting members being designed to bear laterally against the paving and having upper lateral extensions designed to bear upon the top of the paving, and a horizontally movable bridge member carried by one of the supporting members having extension across said interval and a sliding bearing upon the upper lateral extension of the supporting member at this side.

In testimony whereof I afix my signature, in presence of two witnesses. v

THOS. I1. MOORE.
